US Patent:

20140012373, Jan 9, 2014

Filed:

Sep 12, 2013

Appl. No.:

14/025701

Inventors:

Marlowe E. Patterson - Orange CA, US
Stephen C. Geist - Costa Mesa CA, US
Travis Oba - Brea CA, US
David L. Hauser - Newport Beach CA, US

Assignee:

Edwards Lifesciences Corporation - Irvine CA

International Classification:

A61F 2/24

US Classification:

623 238

Abstract:

Embodiments of a method for implanting a prosthetic valve at the native mitral valve region of the heart, the prosthetic valve including a main body that is radially compressible to a radially compressed state and self-expandable from the compressed state to a radially expanded state. The prosthetic apparatus also comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body with a leaflet-receiving space between the anchor and an outer surface of the main body to receive a native valve leaflet. Apparatus for delivering and implanting the prosthetic valve are also described.

Appl. No.:

8/644033

Inventors:

David H. Hauser - Bloomfield Hills MI

International Classification:

E05D 502

US Classification:

16388

Abstract:

A door security device for use in securing a door against unauthorized entry. The device includes a protrusion which can be mounted to the hinge side of a door or to the hinge side of a door frame and can be received within a recess in the opposite door or door frame. The protrusion in received by the recess to prevent the door from being removed by removal of a hinge pin.

International Classification:

A61F 2/24

Abstract:

Disclosed herein are devices for improving coaption of the mitral valve leaflets to reduce or eliminate mitral valve regurgitation. The devices may be used to perform mitral valve annuloplasty, or to serve as a docking station for a transcatheter prosthetic heart valve. The various embodiments of devices are configured for percutaneous and, in some cases, transvascular delivery. Delivery systems useful for routing the devices to the mitral valve are also disclosed, including catheters, balloons and/or mechanical expansion systems. The devices themselves include at least one tissue penetrating member. Methods of delivery include partially embedding the devices in the mitral valve annulus via at least one tissue penetrating member. Tissue penetrating members may be embedded into the tissue in a simultaneous or a nearly simultaneous fashion. Upon embedding, the devices employ various expansion and/or contraction features to adjust the mitral valve diameter. Adjustments may continue until the leaflets fully coapt and the problem of mitral regurgitation is reduced or eliminated.

Abstract:

Methods and devices for increasing flow in the left atrial appendage (LAA) include a conduit directing blood flow from a pulmonary artery into the LAA and/or a conduit drawing blood from the LAA by a Bernoulli effect. In one embodiment, a method comprises implanting a conduit in a pulmonary vein, expanding an inlet portion such that the conduit becomes anchored within the vein and directs blood through an outlet portion of the conduit into or toward the left atrial appendage.
